Slackware is full of documentation, including the man pages, info, pages, html docs, and the included guides. On the root directory of the installation disks you will find many README files that will walk you through numerous tasks including the Installation, Encryption, LVM support, INITRD and raid support. Additionally if you look in the usb-and-pxe-installers directory you will find guides to setting up usb and pxe installations.
You can also review the websites for rworkman (http://rlworkman.net/pkgs/) and alienbob (http://connie.slackware.com/~alien/) for additional guides. These will make your configurations and personalization much simpler. As a note many of these guides can also be useful for replicating the steps on other distros to obtain the same functionality.
Please feel free to share additional guides that you have located within the group, for information is power and we all lust for power.
